Thanks Julius,
We are trying to achieve this in a test system not in production. In production we have controlled emergency use concept. There developers can have debug change authority only in case of emergency. But issue is that its a different team with different geographical location. They are allowed to have access to attachment services as well. We are not. When client is copied the attachments are also copied to test system 
.
Will explore more based on your suggestions.
thanks.
Mrugesh.
